Great, thanks.I find the multi parameter and multi variable nodes much neater than linking several separate nodes.By the way, I think my debug_tool node is very useful, too. Have you tried it?

I've been thinking of Bezier curve support. But maybe it would be better to allow compatibility with, say, Inkscape. I think it should be possible to write an Inkscape extension to get it to export a 2D shape as a scad file containing a 2D polygon. I have written Inkscape extensions (to export Gcode, as it happens). They use python.If I can find time, I could look into creating an Inkscape-to-scad exporter, si vous voudriez.Chris
